6.1.22

bhāvajijñāsārthaṃ praicārakamukhān saṃvāhakagāyanavaihāsikān gamye tadbhaktān vā praṇidadhyāt/

Now a courtezan should not sacrifice money to her love, because money is the chief thing to be attended to. But in cases of fear, etc., she should pay regard to strength and other qualities. Moreover, even though she be invited by any man to join him, she should not at once consent to an union, because men are apt to despise things which are easily acquired. On such occasions she should first send the shampooers, and the singers, and the jesters, who may be in her service, or, in their absence the Pithamardas, or confidants, and others, to find out the state of his feelings, and the condition of his mind. By means of these persons she should ascertain whether the man is pure or impure, affected, or the reverse, capable of attachment, or indifferent, liberal or niggardly; and if she finds him to her liking, she should then employ the Vita and others to attach his mind to her.
